UMF vs MGO: What’s the Difference and How Do They Compare?

When choosing Manuka honey, two terms often appear: UMF and MGO. While they are related, they measure different aspects of Manuka honey, and understanding the difference can help you make a more informed choice.

In this guide, we explain what UMF and MGO mean, how they relate to each other, and how they are used to describe Manuka honey quality.

What Is UMF?

UMF stands for Unique Manuka Factor. It is a grading system developed in New Zealand to measure the authenticity and quality of Manuka honey.

UMF is based on a range of identifying markers, including:

• Methylglyoxal (MGO)
• DHA (dihydroxyacetone)
• Leptosperin (a key Manuka marker)

Because it includes multiple components, UMF is considered a broader certification system that helps verify both the origin and composition of Manuka honey.

What Is MGO?

MGO refers to methylglyoxal, a naturally occurring compound found in Manuka honey. It is one of the key components associated with Manuka honey’s unique properties.

MGO is measured in mg/kg, indicating the concentration of methylglyoxal in the honey.

Unlike UMF, MGO is a single measurement rather than a certification system.

UMF vs MGO: What’s the Difference?

The main difference is that UMF is a multi-factor grading system, while MGO measures one specific compound.

• UMF: A broader quality and authenticity certification
• MGO: A measurement of methylglyoxal content

Because methylglyoxal is one of the components included in the UMF grading process, the two values are related but not identical.

UMF to MGO Conversion Guide

While UMF and MGO measure different things, approximate comparisons are often used as a guide:

These values are approximate and can vary slightly depending on the specific product and testing methods used.

Which Is Better: UMF or MGO?

Rather than one being better than the other, UMF and MGO serve different purposes.

UMF provides a more comprehensive certification of authenticity and quality, while MGO offers a clear indication of the level of one key compound within the honey.

Both are useful, and understanding how they relate can help you choose a product that meets your preferences.

Understanding Manuka Honey Quality

When selecting Manuka honey, it is important to consider both certification and composition. Looking at UMF, MGO and overall product quality together can provide a more complete picture.

By understanding these terms, you can make more informed decisions and better appreciate what makes Manuka honey unique.
